Can’t add creative to set

If you can’t add a creative (video, HTML, or image) to a creative set, it is likely because the asset is marked as “Rejected” in the Status column of the Media Library.

AppLovin automatically reviews creatives you upload to the platform for their compliance with creative policies. If an asset violates these policies, it is marked “Rejected”. Rejected assets cannot be added to creative sets, which may prevent the campaign from serving impressions.

To ensure your creative assets are not rejected, familiarize yourself with AppLovin’s demand policies.
